If the promotions were neglible you wouldn't be promoting like you do
You assume I need to act logically. I could be illogical, or act on false assumptions, or have an agenda.
Damage resistance which you get via promotions is everything
But i'm just a professional engineer who can do complex math.
The first statement is wrong. Take the whole picture into account. Increase your perspective from individual system component to system wide and higher level. Goodbye trees, goodbye forest, hello Biome.
Let me count the ways damage can be avoided, mitigated ,or reduced. In no particular order, and this is not an exhaustive list, and I have been meaning to type some of these anyway. This is not even taking into account the possibility MP personal damage resistence is capped at 80%
0. Not aggro'ed
Aggro manipulation is awesome. I can bump into enemies engaged in others, even attack them, and while they're still on their initial attack animation/engagement, they will not retaliate until that engagement is complete.
Lol-Kite the Zone 5 Commander forever while my teammates smash them to pieces. Enemies are dumb.
1. Being out of range.
I take two steps outside a brute's weapon range while he swings wildly, he whiffs
2. Movement
Any movement away from a stalker will cause the daggers to miss and damage be avoided, especially as it uses twin fangs
3. Barrier. nuff said
4. Weaken / enemy debuff
Certain passives allow for (presumably) unlimited stacks of damage reduction, and improved weaken status effect is up to 30% weaken
5. Bodyguard
I take half damage, and Templar can take half of that.
6. Cover.
"Name's Sera. This is cover. Get round it" --Sera
7. Cross Combo Primer Incapacitates
Weaken+Shock=Sleep
Paralyze
Freeze
Stun
8. Knockdown
CHARRRRGE!
9. Killing the enemy
10. Abilities with Block (and slash for katari) / Damage interruptors
Oh sorry, your attacks are rendered meaningless. Have some counterattack punishment.
11. Stagger
12. Watching the enemy behaviour and animations
Walk around like a fool with back turned. Turn around. See Katari. See Katari Run. Yell at Katari while standing in place and rabble rousing arm in air. Watch as Katari spits at you face to face. Raise arm to wind up sword or bow. Get knocked down by Katari Charge as staring at Katari, yelling and screaming in mid air. Staring and finally attacking or not attacking as Katari brings up block and slash, is too slow and ineffective to stop Katari from Bullrush Charging and squishing self with Mighty Blow. --Footsoldier/Archer
Brute see Katari. Brute Charge with overhead attack. Katari sidesteps and Brute misses. Brute Mad. Brute Swing three times at Katari. Katari out of range. Brute Madder. Brute stop moving and swing widely three times in air. Katari laughs and roflstomps Brute's comrades, then charges through mighty blow's at a distance outside Brute's wild knockdown swings. Brute mad. Brute insane. Brute repeat same ineffective attack pattern. --Brute MAD raaargh
Stalker says I got him I got the Katari... *whiff*... I don't got him, he's walking slightly forward. Lemme circle round round round. What he combat rolled? Is that a charge or a pommel strike on my hea... Oh I'm dead. That was fast. --Venator Stalker
Rar raaar raaar. I see'm. The katari. Raar. I want to yell at the air. raaar. I iz ztealthy. Dey no see me. raaar. swish swish. N'er my noises and the white target reticule at 5m, nor how I move mostly in a direct line to my target.... Pay no attention to the elemental arrow in my head or the fact that I am burning. no. no. NOOOO Not static caaaage. Noooooo don't charge me! I was going to sewing machine stab that keeper. --Last moments of a Shadow
As much as I like telling these stupid stories, all of those situations aren't helped much by defense. It is an aggregation of all of them (and more I'm not mentioning I'm sure) that make the additional +.5% attributes extremely marginal.
You will likely die if you pay no attention. You will very likely succeed if you do. The stats and gear help, but becoming a strong player is the first order of business, and the character / gear development is secondary.
